下面参考图1和图2描述根据本发明实施例的制冷设备100。需要说明的是，该制冷设备100不仅可以具有制冷功能，还可以具有制热功能。可选地，该制冷设备100可以是任何利用空气换热器的设备、装置等，例如可以是空调器室内机、空调器室外机、冰箱等产品。
如图1所示，根据本发明实施例的制冷设备100，包括：壳体1和换热器组件2。壳体1上设有通风口11，换热器组件2设在壳体1内。
如图1所示，通风口11可以设置在壳体1顶部，通风口11可以用于制冷设备100进风。换热器组件2包括：分流换热器21、近风换热器22、背风换热器23和第一连通管24。
进一步地，如图1和图2所示，作为本发明的一个可选的示例，通风口11可以形成在壳体1的顶部且机壳从通风口11进风，从壳体1的其他部位(例如下部)出风。换热器组件2设在壳体1内且与通风口11相对。
分流换热器21具有邻近通风口11的近风部211和远离通风口11的背风部212，分流换热器21上设有供制冷剂进入的分流换热器入口213，近风部211上设有供制冷剂流出的近风部出口214，背风部212上设有供制冷剂流出的背风部出口215。
背风换热器23距通风口11的距离大于近风换热器22距通风口11的距离，即近风换热器22邻近通风口11设置，背风换热器23远离通风口11设置。近风换热器22连接在分流换热器21的近风部211上，近风换热器22上设有供制冷剂流入的近风换热器 入口221和供制冷剂流出的近风换热器出口222，背风换热器23连接在分流换热器21的背风部212上，背风换热器23上设有供制冷剂流入的背风换热器入口231和供制冷剂流出的背风换热器出口232。
可选地，部分制冷剂可以分别进入到分流换热器21、近风换热器22和背风换热器23内，并且分别从分流换热器21、近风换热器22和背风换热器23中排出。这样每个换热器可以具有互不影响的制冷剂流路。当然本发明并不限于此，分流换热器21、近风换热器22和背风换热器23之间可以相互连通，以使制冷剂在分流换热器21、近风换热器22和背风换热器23内依次进行换热。
参见图1所示的示例，通风口11形成在机壳顶部，可选地，分流换热器21相对于竖直方向倾斜布置，近风换热器22相对于竖直方向倾斜布置且与分流换热器21呈倒“V”形布置。其中分流换热器21的上部即为近风部211，分流换热器21的下部即为背风部212，近风换热器22与分流换热器21的上部相连且倾斜布置，背风换热器23与分流换热器21的下部相连，可选地，背风换热器23的至少一部分大致沿竖直方向延伸，参考图1所示，背风换热器23的上段大致沿竖直方向延伸，背风换热器23就的下段倾斜延伸。
需要说明的是，由于换热器组件2中的分流换热器21、近风换热器22和背风换热器23具有上述的结构和位置关系，从而就决定了分流换热器21、近风换热器22和背风换热器23中越临近通风口11的位置，换热效果相对越好，越远离通风口11的位置，换热效果相对越差。具体而言，对于分流换热器21而言，其近风部211的换热效果好于其背风部212的换热效果，近风换热器22的换热效果好于背风换热器23的换热效果。
为了提高分流换热器21、近风换热器22和背风换热器23的换热均匀性，在本发明的实施例中，第一连通管24的两端分别连通背风部出口215和近风换热器入口221、以将从背风部出口215流出的制冷剂引导至近风换热器22内。这样，可以将背风部212的原本换热效果不好的制冷剂引导至近风换热器22内部进行换热，以提高背风部212的制冷剂的换热效果，由此提高整个换热器组件2的换热均匀性。
根据本发明实施例的制冷设备100，由于换热器组件2中通过设置可以连通背风部出口215和近风换热器入口221的第一连通管24，从而可以提高换热器组件2的换热均匀性，可以提高整个制冷设备100的性能。
在本发明的第二个实施例中，制冷设备100中还可以包括第二连通管25，第二连通管25的两端分别连通近风部出口214和背风换热器入口231、以将从近风部出口214流出的制冷剂引导至背风换热器23内。这样，可以将近风部211的原本换热效果好的 制冷剂引导至背风换热器23内部进行换热，从而通过第一连通管24和第二连通管25，从而可以进一步提高整个换热器组件2的换热均匀性，进而提高换热效率。
可选地，从背风部出口215流出的部分制冷剂可以向下流动至背风换热器23内进行换热，从近风部出口214流出的部分制冷剂可以向流动至近风换热器22内进行换热。
当然本发明并不限于此，从背风部出口215流出的全部制冷剂可以通过第一连通管24引导至近风换热器22进行充分换热，从近风部出口214流出的全部制冷剂可以通过第二连通管25引导至背风换热器23进行热交换，由此可以使换热器组件2的换热均匀性更加明显。
可选地，如图1和图2所述，分流换热器21内可以设有分流三通管216，分流三通管216中的三个开口分别与分流换热器入口213、近风部出口214和背风部出口215连通。制冷剂通过分流三通管216从分离换热器入口分别通过近风部出口214和背风部出口215排出，从而可以使分流换热器21的结构紧凑、合理，分流换热器21的布置空间小。
可选地，近风换热器入口221位于近风换热器出口222的上方，背风换热器入口231位于背风换热器出口232的上方。如图1所示，近风换热器22具有两排换热流路，制冷剂从近风换热器入口221进入后先在近风换热器22的邻近通风口11的一侧(邻近近风换热器22的外表面)流路内流动换热，再流向近风换热器22的背离通风口11的一侧(邻近近风换热器22的内表面)流路内流动换热，由此可以使制冷剂换热效果好。同理，背风换热器23具有两排换热流路，制冷剂从背风换热器入口231进入后先在背风换热器23的邻近通风口11的一侧(邻近背风换热器23的外表面)流路内流动换热，再流向背风换热器23的背离通风口11的一侧(邻近近风换热器22的内表面)流路内流动换热，由此可以使制冷剂换热效果好。
可选地，如图1和图2所示，制冷设备100还可以包括辅助换热器26，辅助换热器26设在分流换热器21的邻近通风口11的主表面(即分流换热器21的面积最大的表面)上，辅助换热器26具有供制冷剂流入的辅助换热器入口261和供制冷剂流出的辅助换热器出口262，辅助换热器出口262与分流换热器入口213连通。由此，制冷剂可以优先经过辅助换热器26进行换热，再进入到分流换热器21进行换热、分流，由此可以提高换热器组件2的换热效果，换热效率高。
下面描述根据本发明第二方面实施例的用于制冷设备100的换热器组件2。
制冷设备100包括壳体1，壳体1上设有通风口11，换热器组件2设在壳体1内，可选地，换热器组件2包括：分流换热器21、近风换热器22、背风换热器23和第一连 通管24。
分流换热器21具有邻近通风口11的近风部211和远离通风口11的背风部212，分流换热器21上设有供制冷剂进入的分流换热器入口213，近风部211上设有供制冷剂流出的近风部出口214，背风部212上设有供制冷剂流出的背风部出口215。
背风换热器23距通风口11的距离大于近风换热器22距通风口11的距离，即近风换热器22邻近通风口11设置，背风换热器23远离通风口11设置。近风换热器22连接在分流换热器21的近风部211上，近风换热器22上设有供制冷剂流入的近风换热器入口221和供制冷剂流出的近风换热器出口222，背风换热器23连接在分流换热器21的背风部212上，背风换热器23上设有供制冷剂流入的背风换热器入口231和供制冷剂流出的背风换热器出口232。
需要说明的是，分流换热器21、近风换热器22和背风换热器23均为空气型换热器，也就是说，制冷剂流动在分流换热器21、近风换热器22或背风换热器23内部，分流换热器21、近风换热器22和背风换热器23通过与空气换热从而对其内部的制冷剂进行蒸发或冷凝。可选地，分流换热器21、近风换热器22和背风换热器23可以是翅片式换热器。当然本发明并不限于此，分流换热器21、近风换热器22和背风换热器23还可以是吹胀式换热器、微通道换热器等。
需要说明的是，由于换热器组件2中的分流换热器21、近风换热器22和背风换热器23具有上述的结构和位置关系，从而就决定了分流换热器21、近风换热器22和背风换热器23中越临近通风口11的位置，换热效果相对越好，越远离通风口11的位置，换热效果相对越差。具体而言，对于分流换热器21而言，其近风部211的换热效果好于其背风部212的换热效果，近风换热器22的换热效果好于背风换热器23的换热效果。
为了提高分流换热器21、近风换热器22和背风换热器23的换热均匀性，在本发明的实施例中，第一连通管24的两端分别连通背风部出口215和近风换热器入口221、以将从背风部出口215流出的制冷剂引导至近风换热器22内。这样，可以将背风部212的原本换热效果不好的制冷剂引导至近风换热器22内部进行换热，以提高背风部212的制冷剂的换热效果，由此提高整个换热器组件2的换热均匀性。
根据本发明实施例的换热器组件2中通过设置可以连通背风部出口215和近风换热器入口221的第一连通管24，从而可以提高整个换热器组件2的换热均匀性。
在本发明的第二个实施例中，换热器组件2中还可以包括第二连通管25，第二连通管25的两端分别连通近风部出口214和背风换热器入口231、以将从近风部出口214流出的制冷剂引导至背风换热器23内。这样，可以将近风部211的原本换热效果好的 制冷剂引导至背风换热器23内部进行换热，从而通过第一连通管24和第二连通管25，从而可以进一步提高整个换热器组件2的换热均匀性，进而提高换热效率。
可以理解的是，根据本发明实施例的换热器组件2可以应用到任何制冷设备100中以提升各种制冷设备100的性能。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
